drm/amdgpu/display: drop DCN support for aarch64

2021-01-06T21:24:10Z

From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64. Acked-by: Will Deacon Reported-by: Ard Biesheuvel Signed-off-by: Alex Deucher

drm/amd/display: add DCN support for aarch64

2020-08-10T21:26:53Z

This adds ARM64 support into the DCN. This mainly enables support for Navi graphics cards. The dcn10 changes haven't been tested, since I don't have the relevant hardware available, but there is no way to conditionally disable them, so I've done them anyway.

drm/amd/display: cleanup of function pointer tables

2019-11-19T15:12:53Z

[Why] It is becoming increasingly hard to figure out which function is called on the different DCN versions [How] 1. Make function pointer table init in its own init.c file 2. Remove other scenarios in hwseq.c file that need to include headers of other DCN versions. (If needed, it should have been done via the function pointers) Signed-off-by: Anthony Koo Reviewed-by: Aric Cyr Acked-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amd/display: make clk mgr soc specific

2019-05-31T15:39:29Z

[Why] First step of refactoring clk mgr to better handle different ways of handling clock operations. Clock operation policies are soc specific and not just DCN vesion specific. It is not a hw resource, should not be in the resource pool. [How] Change clock manager creation to be based on HW internal ID, rename clock manager members to be more clear. Move clock manager out of resource. Signed-off-by: Eric Yang Reviewed-by: Tony Cheng Acked-by: Leo Li Signed-off-by: Alex Deucher

drm/amd/display: rename dccg to clk_mgr

drm/amd/display: implement DPMS DTN test v2

2018-08-27T16:11:07Z

[why] Existing DTN infrastructure in driver is hacky. It uses implicit log names, and also incorrect escape ID. [how] - Implement using generic DTN escape ID. - Move file logging functionality from driver to to script; driver now outputs to string/buffer - Move HWSS debug functionality to separate c file - Add debug functionalty for per-block logging as CSV - Add pretty print in python Signed-off-by: Jun Lei Reviewed-by: Tony Cheng Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher
